Chances at Stern

<p>So currently I'm a student at private school in NYC hoping to get into Stern next year (I'm a junior). My first two years of high school I averaged around a b-/b average, but this year I have significantly turned around all of my grades and my average is around A- (93%). If I keep up my 92/3% average and do well on my sat (above 2k), what are the chances I can get into NYU stern. Also my school does not calculate GPA on the college transcript.</p>

<p>Do you think my freshman and sophomore year messed up my chances?</p>
